Why Meta AI Matters for CMOs
Meta AI reaches people inside Facebook, Instagram, WhatsApp and Messenger. When those buyers ask it which vendor to use, it answers from Meta AI search, which Meta-WebIndexer crawls for, so your brand is either in that answer or a competitor is. For a CMO that turns Meta AI into a share-of-voice channel you can track alongside organic and paid, not a technical detail to delegate.
The Meta AI Mistake to Avoid
Confusing Meta-ExternalAgent with Meta-WebIndexer. Meta-ExternalAgent only collects training data, while Meta-WebIndexer decides whether pages can appear in Meta AI answers. Blocking the wrong one either removes you from answers or leaves training access open when you meant to close it.

Frequently Asked Questions
How should a CMO measure Meta AI visibility?
Keep a fixed set of buying-intent prompts, run them in Meta AI on a schedule, and log how often your brand is named, where it sits among named vendors, and whether the description is accurate. A stable prompt set is what makes quarter-over-quarter changes meaningful.
What decides whether Meta AI can mention our brand at all?
Meta documents separate agents: Meta-WebIndexer improves Meta AI search results, Meta-ExternalAgent collects training data, and Meta-ExternalFetcher fetches pages on a user's request and may bypass robots.txt. Beyond access, Meta AI can only repeat what your public pages state clearly, so a vague positioning page limits what it can say about you.
